Procedure

4-Hydroxyaniline (11 mmol), 4,7-dichloroquinoline (10 mmol ), 1 ml of 2N hydrochloric acid, and catalytic amounts of potassium iodide were refluxed in acetone for 12 hours. The product was filtered. The product (5 mmol), 3-piperidinopropylchloride hydrochloride (5 mmol), potassium carbonate (15 mmol), and catalytic amounts of potassium iodide were refluxed in acetone for 22 hours. The product was filtered and purified by flash chromatography (eluent: methylene chloride/petroleum ether/triethylamine (95/25/5)). The solvent was removed under reduced pressure. The residue was crystallized with oxalic acid from diethyl ether/ethanol.
